"...Ebola virus and other pathogens disappeared from the Army's biological warfare research facility in the early 1990s..."

"Not in dispute is what the incidents say about disorganization and lack of security in some quarters of the U.S. Army Medical Research Institute of Infectious Diseases -- known as USAMRIID -- at Fort Detrick, Md., in the 1990s. Fort Detrick is believed to be the original source of the Ames strain of anthrax used in the mail attacks last fall, and investigators have questioned people there and at a handful of other government labs and contractors."

Lab specimens of anthrax spores, Ebola virus and other pathogens disappeared from the Army's biological warfare research facility in the early 1990s, during a turbulent period of labor complaints and recriminations among rival scientists there, documents from an internal Army inquiry show.

The 1992 inquiry also found evidence that someone was secretly entering a lab late at night to conduct unauthorized research, apparently involving anthrax. A numerical counter on a piece of lab equipment had been rolled back to hide work done by the mystery researcher, who left the misspelled label ``antrax'' in the machine's electronic memory, according to the documents obtained by The Courant.

Experts disagree on whether the lost specimens pose a danger. An Army spokesperson said they do not because they would have been effectively killed by chemicals in preparation for microscopic study. A prominent molecular biologist said, however, that resilient anthrax spores could possibly be retrieved from a treated specimen.

In addition, a scientist who once worked at the Army facility said that because of poor inventory controls, it is possible some of the specimens disappeared while still viable, before being treated.

"Many of the specimens were tiny samples of tissue taken from the dead bodies of lab animals infected with deadly diseases during vaccine research. Standard procedure for the pathology lab would be to soak the samples in a formaldehyde-like fixative and embed them in a hard resin or paraffin, in preparation for study under an electron microscope."

"Rosenberg's analysis of the anthrax attacks, which has been widely reported, concludes that the culprit is probably a government insider, possibly someone from Fort Detrick. The Army facility manufactured anthrax before biological weapons were banned in 1969, and it has experimented with the Ames strain for defensive research since the early 1980s."

More troubling to Langford than the missing specimens was what investigators called ``surreptitious'' work being done in the pathology lab late at night and on weekends. Dr. Mary Beth Downs told investigators that she had come to work several times in January and February of 1992 to find that someone had been in the lab at odd hours, clumsily using the sophisticated electron microscope to conduct some kind of off-the-books research. After one weekend in February, Downs discovered that someone had been in the lab using the microscope to take photos of slides, and apparently had forgotten to reset a feature on the microscope that imprints each photo with a label. After taking a few pictures of her own slides that morning, Downs was surprised to see ``Antrax 005'' emblazoned on her negatives. Downs also noted that an automatic counter on the camera, like an odometer on a car, had been rolled back to hide the fact that pictures had been taken over the weekend. She wrote of her findings in a memo to Langford, noting that whoever was using the microscope was ``either in a big hurry or didn't know what they were doing.''"
